Specification of Letters Patent.

Patented Nov. 15, 1910.

Application filed July 16, 1910. Serial No. 572,330.

To all whom it may concern:

Be it known that I, ANDREW RENIK, a citizen of the United States,residing at Kenosha, in the county of Kenosha, State of Wisconsin, haveinvented certain new and useful Improvements in Rotary Engines; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention relates to rotary engines and has special reference to anovel arrangement of abutment and valves for such an engine.

One object of the invention is to improve the arrangement of abutmentsin an engine of this description.

A second object of the invention is to provide a novel and improved formof control for the steam in such an engine.

lVith the above and other objects in view, as will be hereinafterapparent, the invention consists in general of a stator having anannular steam chamber, a piston provided rotor, and abutments and valvegearing of novel and improved construction.

The invention further consists in certain novel details of constructionand combinations of parts hereinafter fully described, illustrated inthe accompanying drawings, and specifically set forth in the claims.

In the accompanying drawings, like characters of reference indicate likeparts in the several views, and Figure 1 is a vertical section throughan engine constructed in accordance with this invention, the sectionbeing taken transverse the axis of rotation. Fig. 2 isa section on theline 2-2 of Fig. 1. Fig. 3 is an enlarged detail section through thevalves. Fig. a is a detail perspective View of one of the abutments.Fig. 5 is a section through a port-ion of the steam chamber showing theabutments. Fig. 6 is a perspective view of the rotor removed from thestator. Fig. 7 is a section on the line 77 of Fig. 1.

This invention comprises a stator which is preferably made in two partseach of which is indicated by the numeral 10 and these parts are securedtogether by suitable bolts 22 passing through lugs in the base and otherbolts 12 passing through flanges 13 formed around the periphery of thebody, the latter being circular in outline. Extending around each of theparts 10 is an annular channel 11, the two channels being so positionedthat when the parts are together the channels form an annular steamchamber substantially circular in cross section. Centrally of the bodyof the stator there is provided a pair of alined bearings 14 throughwhich passes a shaft 15. In the space between the channels 11 and theshaft 15 the stator halves 10 have their inner faces spaced apart asindicated at 16.

The rotor comprises a disk 17 having cam portions 18 formed thereon,these cam portions serving to support pistons 19. These cam portions 18are furthermore provided in certain instances with wings 18 which serveto better direct and distribute the incoming steam as well as to add tothe efliciency of the engine. The pistons 19 fit closely in the annularsteam chamber and in order to prevent steam from leaking down into thespace wherein the disk 17 rotates suitable packing strips 20 areprovided which extend around the inside of the stator,

one of these strips being shown clearly in its relation to the parts inFig. 1. This rotor is secured to the shaft by means of a suitable key 21so that as the rotor is moved the shaft 15 will revolve.

At one side of the stator there is provided an opening 22 and coveringthis opening is a steam chest 23 fitted with a suitable cover 2 1. Thissteam chest is divided by a partition 25 into two parts and thispartition carries casings 26 wherein are guide members 27 The casings 26are each provided with an opening 28 which leads from the body of thesteam chest into the casing.

The partition 25 extends into the opening 22 and slidable through thetwo parts of this opening, thus divided by the partition, is a pair ofabutments 29. Each of these abutments has a fiat back which restsagainst the partition and a squared end 30 which fits closely in thesteam chamber when the abutment is projected inward. Through eachabutment extends a steam passage 31 having a lateral opening 32 which isadapted to register with the respective opening 28 when the abutment isin its inward position. The steam passage, furthermore, has an opening33, this latter opening affording communication with the steam chamberof the stator. Projecting from each of the abutments and through therespective guides 27 are stems 3 1 and surrounding these stems are coilsprings 35, one end of each spring bearing a handle port-ion 42 and onthis link is a while when the valves are rotated ninety through what waspreviously the exhaust 5 of Fig. 1 and cause the stator to rotate in aagainst the end of a respective abutment while the other end of saidspring bears against the respective guide 27. ,By this means theabutments are constantly urged to their inward position.

Extending through the head 2st are steam pipes 36 which are connected totwo-way valves 37 each having a handle 38. Extending from each of thetwo-way valves 37 is an exhaust pipe 39 and communicating with saidvalves are steam pipes 40. The handles 38 are connected by a link 41provided with projection 43 adapted to engage in one of the notches 44of a plate 45 fixedly secured in the path of said projection 43. Bymeans of the link 41 the two valves may be simultaneously actuated andfrom an inspection of Fig. 3 it will be noted that when the valves arein the position there indicated steam will be admitted to one side ofthe steam chest and exhausted from the other degrees the two sides ofthe steam chest will act in the opposite manner, that is to say, steamwill be exhausted from what was previously the admission side andadmitted side. 1

In the operation of the device let it be assumed that the parts are inthe positions indicated in Figs. 1 and 3. Steam will then flow in thedirection of the arrows from the pipe 36 through the registeringopenings 28 and 32, thence through the abutment and into the steamchamber of the stator. Here the steam will act against the upper piston19 direction opposite the hands of a clock. Meanwhile the steam whichhas been previously admitted to the steam chamber will follow thedirection of the arrows shown below the abutments and pass out throughthe lower abutment, registering ports 32 and 28 and the exhaust side ofthe steam chest 23. As the rotor continues its movement the cam portions18 will force the abut-ments outward against the action of the springsThis will close off both the valves formed by these abutments and thecasings 26 and the inertia of motion in the rotor will carry the partsaround until the abutments are again moved inward and the ports 28 and32 brought into registry. Then this takes place a further supply ofsteam will be admitted and the other piston 19 will be im- 1 pelledaround. In case that it is desired to use the engine for movement onlyin one direction the cam portions 17 may be modified by the omission ofalternate portions so that the abutments will move abruptly back afterthe piston 19 has passed. In this case the valve arrangement may also beeliminated as one of the pipes 36 will always be the steam supply pipeand the other will always be the exhaust pipe.

There has thus been provided a simple and efficient device of the kinddescribed and for the purpose specified.

It is obvious that minor changes may be made in the form andconstruction of this invention without departing from the materialprinciples thereof. It is not therefore desired to confine the inventionto the exact form herein shown and described, but it is wished toinclude all such as properly come within the scope of the appendedclaims.

Having thus described the invention, what is claimed as new, is V 1. Ina rotary engine, a stator having an annular steam chamber, a steam chesthaving a pair of spaced openings communicating with said chamber, apartition in said steam chest between said openings, a casing on eachside of said partition provided with a lateral steam port, a pair ofhollow abutments each mounted to slide in one of said casings andprovided with a steam passage having a lateral port. adapted to registerwith the port of the respective casing, a rotor pro vided with means formoving said abutments outward, springs in said casings urging saidabutments inward, steam pipes communicating with the valve casing oneach side of the partition, and means to control the direction of flowthrough said steam pipes.

2. In a rotary engine, a stator having an annular steam passage, a rotorrevoluble in said stator and provided with a piston moving in saidpassage, a cam rib leading from said piston and provided with a seriesof lateral disposed wings, and an abutment slidable into and out of saidpassage, and means to supply steam to the passage between the abutmentand piston.

In testimony whereof, I affix my signature, in presence of twoWitnesses.
